ExtJs 4.1 : How to send json data in the request body using Ext.Ajax.request()?
提问by leaf
I would like to send json data using Ext.Ajax.request()then access it in ASP.NET using Request.InputStreamwhich is the content of the request body. I need a way to tell ExtJs to write the data in the request body as it is done while using an Ext.data.proxy.Ajax.
我想发送 json 数据，Ext.Ajax.request()然后使用它在 ASP.NET 中访问它，使用Request.InputStream它是请求正文的内容。我需要一种方法来告诉 ExtJs 将数据写入请求正文中，因为它是在使用Ext.data.proxy.Ajax.

Specify POSTmethod and just use the request's jsonDataconfig:
指定POST方法并只使用请求的jsonData配置：
Ext.Ajax.request({
url: 'myUrl',
method: 'POST',
params: {
requestParam: 'notInRequestBody'
},
jsonData: 'thisIsInRequestBody',
success: function() {
console.log('success');
},
failure: function() {
console.log('woops');
}
});
If you want a recordwritten as JSON you can use a JSON writer like this also.
如果您想要将记录写为 JSON，您也可以使用这样的 JSON 编写器。
var writer = Ext.create('Ext.data.writer.Json'),
record = Ext.getStore('SomeStoreID').first();
Ext.Ajax.request({
url: 'myUrl',
method: 'POST',
params: {
requestParam: 'notInRequestBody'
},
jsonData: writer.getRecordData(record),
success: function() {
console.log('success');
},
failure: function() {
console.log('woops');
}
});
